title: [Adenocarcinoma developed in the pulmonary giant bulla; report of a case].
abstract: A 56-year-old man was point out chest abnormal shadow in the left lung by chest X-ray for routine follow-up of diabetes. Chest computed tomography (CT) revealed emphysematous changes in the bilateral lung, and showed an approximately 23 x 20 mm tumor in the giant bulla of the left upper lobe. Left S(1+2) segmentectomy was performed as the diagnosis of adenocarcinoma was established by intra-operative biopsy. The lesion was diagnosed as poorly differentiated adenocarcinoma (pT1N0M0P0D0PM0E0, stage IA). The frequency of lung cancer within a bulla is reported as high as 14-29% in Japan. Therefore, it is thought to be necessary that the pulmonary bullous lesion must be followed-up for a long period because of the possibility of development of malignancy.
